Via Joel Sherman, the Yankees have decided that Curtis Granderson will start the season as the every day centerfielder, pushing the incumbent Brett Gardner to left. He notes that Granderson’s sometimes awkward routes have improved as camp has progressed, and the Yanks didn’t feel it was enough of an upgrade defensively to make the switch. The move will probably cost the Yankees something like five runs defensively over the course of the season, though we don’t have enough reliable data on Gardner’s defense to say with any certainty.
I guess the biggest thing is just making sure Granderson was comfortable. There’s no need to move him back and forth between center and left depending on who else was playing the outfield on a given day (Gardner, Randy Winn, Marcus Thames), the guy will have enough to get used to in his first season in New York as it is.
